Condensate pump running
Comments (4)Does your furnace vent up a chimney or out the wall? If it's high efficiency using through-the-wall venting it will produce condensate that needs to be drained periodically. the pump shouldn't run constantly--that's a pump problem that won't be solved by wiring it differently. FWIW, replacements cost less than $100 generally and you can install yourself if you're mildly handy....See MoreTACO circulator pump running constantly
Comments (14)Yes if you have a higher pressure it is easer to push the air out. its the same way to circulate, if you pressure is to low it will not want to flow to the upper story, especial if the pump is too small. If you go to the hi velocity pump,and thats what i always use in a three story house, you will have one little thing you may not like. On a zone system , when only one zone is open you might hear a little water movement noise depending on you piping system. Engineering will vary from one engineer to another a little. But i am going to give you some facts. normal hot water system no more than 30' to 40' of radiation on one 3/4 in. loop or zone and standard zone values 3 to 3 1/2 gal.s per min. . Now if you have too long of loop you will slow flow down and lose too much heat, same if you have too much radiation on a loop. You said three story two zones. this sounds like long loops which means hi head pressure, and maybe too much radiation per zone. some times when i run into this i advice the owner that we will have to switch the zone values to a full flow zone value, they go up to about 7 gal.s per min. flow, this along with the hi head pump will take care of too much heat loss,and too much head pressure. I hope all this is not confusing you too much, But hot water in a older home can be a little complicated. and a lot of guys do not understand this. You can check a zone out one way by checking the temp leaving the boiler and then check the temp. coming back from the zone. no more than 15 degrees drop..

Comments (10)We still don't know what kind of pump the OP has. How many are there? If more than one, do all of them cause the same noise? Vibration could be transmitted by all the routes indicated by the OP. Another route is right up the pipes. Changing pumps can have two effects, One is changing the frequency of the vibration generated and the other is changing the mass of the system. Are the pumps mounted on the boiler or the pipes? If you hand a big BG pump on there, the harmonic of the pipes might change enough to eliminate the problem, that will be similar to hanging a big piece of inert metal on the pipe. Right now you might have a system with the motor harmonically coupled to the pipes. If so, you just have to uncouple them one way or another. Can you feel a vibration in the pipe that goes away when the circulator shuts off? Does the vibration in the pipe go away if you wrap your (gloved if necessary) hand around it? What kind of pipe is connected to the pump and does that kind go all the way to what ever is below the floors? What floor does the output pipe from the pump connect to first, the loudest room? If so, the pipe might be vibrating against a joist or something else right there. If so, you might be able to eliminate the transmission some other way, but you might have to cut into a wall or floor to see what is banging against what and eliminate it. Definitely do investigation at the boiler first, less messy and less expensive....See MoreNoisy Compressor in Geothermal Heat Pump
Comments (14)mac I have an Econar GT heat pump in a second floor closet and had noise issues that were aweful. It turned out to be improper vibration dampening when the system was installed. The scroll compessors run between 50 and 60 cycles per second. The 3 stage fan in my 3 ton GT unit runs in the 1100 to 1800 RPM range (or 18 to 30 cycles per second). The guys who did the install laid the GT unit on the floor and put a rubber mat under the base. That mat became essentailly a vibration noise amplifier. I found that rubber can isolate very high frency vibs - not the lower frequnecies. The rubber is recommended at a minimum of 45 Hz - but it really doesn't work well until you get above 60. I know this is the case becuase my loop pumps in the basement run at 60 Hz and they are on rubber mats too - no vibration noise (there is acoustical noise from the impellar spinning - but that has to be dampened by other means). My solution was to jack up the unit - get if off the floor by 5 inches or so - and put vibration isolation mounts with springs on each of the 4 corners. These springs can dampen vibs down to a few Hz and up to 60Hz - they are much more effective then rubber in the frequnecy range of the unit. That fixed the problem. You can still hear the unit for the first 3 to 5 seconds after it first turns on - but once it is in steady state, it purrs. No louder than the hum of a refrigerator. My builder and HVAC contractor were stunned - appranetly they have this same issue in other houses they built with GT where people cannot sleep (but never told me that when they sold me the GT)! I think they owe me one. Your issue sounds similar to mine. Can you describe how the unit was installed - where it is, what is it resting on? What type of floor is it on - is it in a closet? Is the closet insulated? The site I used to but these products is www.acousticalsurfaces.com. Look under Vibration Mounts and then look under Housed Spring Mounts. The product is made by Mason Industries and needs to be chosen carefully based on your units corner weight. You need to determine if the noise you are hearing is acoustic noise or vibration noise. If it is acoustic noise - then you can use sound proofing insulation. If it is vibration noise - then you need dampeners. I used both - the walls of the room have insulation to dampen acoustic noise. The springs dampen vibration noise....See Moresktn77a
